In which two ways is IPv4 and IPv6 traffic handled in a network design that uses QoS
deployment options? (Choose two.)

Youhave been hired to redesign a network due to issues with congestion. How will a router
function if the QoS mechanism of congestion avoidance is integrated into the existing network
design?

Service provider XYZ plans to provide dedicated Internet access and MPLS L3VPN services to
business customers. XYZ has these design specifications:
 MP-BGP running on the core MPLS P routers with external
Internet routes.
 The core network will include 16 Point of Presence IP POPs
throughout the Asia-Pacific region.
 An additional nine non-P routers will use EBGP peering with
multiple providers for Internet traffic.
 An additional 50 PE routers will provide end customers with
dedicated Internet access and L3VPN services throughout the Asia-Pacific
region.
In what two ways can the MP-BGP be removed from the MPLS P core routers and still provide
dedicated Internet access and MPLS L3VPN services? (Choose two.)

Refer to the exhibit.

An enterprise is migrating its single-area OSPF network from a Frame Relay WAN service to anMPLS L3VPN service. Frame Relay will remain in only a few sites that require increased
resiliency via two different WAN connections.
Which feature could be used in the ?MPLS VPN service provider network to support the design
requirement by ensuring that during normal operation, intersite traffic will only use the MPLS
VPN service and not the old Frame Relay service?

When creating a network design that routes an IGP over L2VPNs, with which device does the
remote CE router form an IGP adjacency?

A company wants to connect two data center sites using a hub-and-spoke design with 2000
remote sites. One design consideration is the requirement to transfer MPLS packets over the
public Internet. In addition, one router at each site should be used, and the MPLS packets must
be encapsulated inside IP packets because the public Internet cannot transfer native MPLS
packets. Which feature can be used to simplify the network design?

You are working on a network design plan for a company with approximately 2000 sites. The
sites will be connected using the public Internet. You plan to use private IP addressing in the
network design, which will be routed without NAT through an encrypted WAN network. Some
sites will be connected to the Internet with dynamic public IP addresses, and these addresses
may change occasionally. Which VPN solution will support these design requirements?

Company X will be integrating an IPv6 application into their network and wants to develop a
test environment to evaluate application performance across the network. This application will
require both unicast and multicast communications. The company can do this implementation
only in certain areas of its existing IPv4-only network, but wants all areas to communicate with
each other. When developing the design to provide connectivity between these testinglocations, what tunneling technology would work in this scenario?

A network designer has provisioned a router to use IPsec to encrypt the traffic over a GRE
tunnel going to a web server at a remote location. From the router,the network designer can
ping the web server, although the users in the office comment that they are unable to reach it.
(Note: The DF bit is not set.) Which aspect should be changed in the design of the virtual
connection?

You are designing a network using multipoint GRE tunnels and need to be able to detect when
connectivity between the GRE tunnel endpoints is broken. Which statement is true about
configuring keepalives for multipoint GRE tunnels?
